Description

The flexible configuration of HARQ procedure feedback

Technical field

Presently disclosed technology relates generally to cordless communication network, and more specifically in relevant such network HARQ（ARQ）The technology of feedback.

Background technology

HARQ（ARQ）It is the error control technique used in many wireless networks.By ARQ, data are passed The receiver sent, which is sent, to be confirmed（ACK）Or NACK（NACK）（Referred to as " ARQ feedback "）, to notify conveyer whether just Really receive each message.Then can retransfer the message and unacknowledged message at all of incorrect reception.

Mix ARQ (HARQ)（It is understood to be the ARQ of improved form）By basic ARQ technologies and data described above Forward error correction (FEC) coded combination of message, to improve the ability that receiver received and be correctly decoded transmission message.With by normal Advise ARQ the same, after each trial decoding message, ACK and NACK is sent using HARQ receiver, depended on the circumstances.This A little ACK and NACK are referred to as " HARQ feedback ".

Third generation partner program（3GPP）Member developed and deployed fourth-generation system（It is widely referred to as LTE （Refer to Long Term Evolution））, and it is formally known as the UMTS terrestrial radio access networks network (E-UTRAN) of evolution.Now in LTE Downlink transmission, depend on whether for up-link PUSCH transmission scheduled UE, HARQ feedback is physically gone From UE on link control channel (PUCCH) or physical uplink link shared channels (PUSCH)（User equipment-mobile terminal 3GPP terms）It is sent to network.

For each downlink transmission to UE, depend on whether to have correctly received transmission, UE will transmit ACK or NACK.Network is except detection ACK or NACK, moreover it is possible to draw the following conclusions：UE does not receive correspondence downlink allocation appropriately, and And so as to not attempt the data-message of demodulation and decoding transmission even（If network is not detected by from the anti-of UE when being expected Feedback）.It is noted, however, that the ACK/NACK detections lost on network side may also be due to that network can not appropriately receive it, although It is transferred by UE.

The NACK that network is received will be triggered and retransmitted, and ACK reception allows to refresh and transmits (Tx) mistake with corresponding HARQ instance again Journey.Pass through conversion（toggle）NDI in next downlink allocation of corresponding HARQ instance process（New data indicator）Mark connects Same new data, and be refreshed and used again from the lateral UE instructions HARQ Tx processes of network.This will connect again UE refreshings HARQ (Rx) process of receipts, and by the data newly received and current HARQ Rx procedure correlations.

As described above, when desired network from UE receive ACK/NACK failure be that UE is correctly decoded downlink The instruction that assignment message may fail, it is in LTE in physical downlink control channel (PDCCH) or enhancing PDCCH (ePDCCH) sent on.This condition is detected so as to the purpose for PDCCH/ePDCCH link circuit self-adaptings in network --- That is, the robustness for adapting to carry the physical control channel that downlink is permitted.

When LTE is based on the fixation between up-link and downlink（Or it is semi-static）During division, other systems and not The LTE for carrying out version can the division based on dynamic dispatching between up-link and downlink.In such systems, in downlink Man-to-man corresponding relation may be not present between transmission and HARQ feedback message.

In LTE upcoming enhancing, it is assumed that operator scheme be dynamic Time Division duplex（TDD）, wherein for upper Line link and downlink are used can dynamically distributes subframe.By this method, HARQ procedure quantity quite can significantly increase, For example because a considerable amount of TTI that can be into downlink allocation a line（TTI）.This makes required HARQ mistakes The quantity of journey increases, because there is long gap between feedback chance in the uplink, to discharge HARQ procedure.

The content of the invention

The downlink load weight situation of the given enhancing LTE system using dynamic TDD, TDD configurations will cause many sons Frame is used for downlink, and relatively little of subframe will be used for UL and use.Therefore, can be relatively less frequent in the uplink Ground provides HARQ feedback, and which in turns increases the importance of their Successful deliveries.Further, since a large amount of movable HARQ in UE Rx processes, may require feedback at any given time for it, HARQ feedback report will be quite big.Presently disclosed technology Some embodiments by using for the clear and definite of HARQ ARQ feedback（explict）Request, solves these and asks Topic, the request indicates one or more ARQ processes.In LTE contexts, this ARQ feedback can be HARQ feedback, but will recognize Know, technique described herein more generally can be applied to support other forms ARQ（With multiple while ARQ processes）Be System.

As discussed above, current LTE system carries out downlink transmission using HARQ, and wherein HARQ feedback is up Sent in link by UE.Downlink scheduling is carried out in 1 millisecond of sub-frame basis.The each frame of scheduling message is sent, and The resource block pair that the resource of allowance distributes to UE in down-chain resource allowance takes all orthogonal frequencies for distributing to PDSCH Divide multiplexing（OFDM）Symbol.It is 3 millis to allow terminal to complete to the processing time of all processing related to the transmission in stator frame Second（Less than timing advance）, it is to cause（account for）The transmission timing adjustment of propagation delay between terminal and base station. LTE specification should be passed in UL so as to provide in response to the ACK/NACK of the PDSCH transmission in subframe n in subframe n+4 Send, the quantity or the size of transmission block permitted regardless of additional downlink resource.This is illustrated in Fig. 4.Develop The deformation of this universal synchronous scheme, to adapt to time division duplex（TDD）Operation and carrier aggregation technology, any of which It can all require to transmit the ACK/NACK of multiple subframes and/or carrier wave in single uplink sub-frames.

As discussed above, LTE system in addition（And other wireless systems）Dynamic TDD can be used, wherein can be On dynamic basis given sub-frame is used for downlink or up-link（Or other TTI TTI）.It is given to use The downlink load weight situation of dynamic TDD enhancing LTE system, TDD, which is used, will cause many sub-frame configurations to be used for descending chain Road is used, and relatively little of subframe will be configured to UL and use.Therefore, it can provide relatively less frequently in the uplink HARQ feedback, which in turns increases the importance of their Successful deliveries.Further, since a large amount of movable HARQ Rx mistakes in UE Journey, may require feedback at any given time for it, HARQ feedback report will be a considerable amount of.

For that can have the network controlled completely to the HARQ feedback of offer, therefore it can expect：

A) for can clearly ask the network of HARQ feedback from UE, for specific HARQ process；

b）In the case where report is not successfully received, repeatedly request can be carried out for same HARQ procedure and is attempted；

c）The HARQ procedure of report is only restricted in those of actual use；And

d）By postponing the request of desired additional process time amount, constrained to loosen UE downlink processing times.

However, these are impossible under the 3GPP LTE as today, because HARQ feedback is synchronous, and pass every time Trial is sent only to transmit once.

According to some embodiments of presently disclosed technology, these problems are by allowing network clearly from movable HARQ mistakes Journey（Or be more generally ARQ processes）Ask HARQ feedback（Or be more generally ARQ feedback）To solve, i.e. for network Through those processes for its trial transmission and possible subsequent re-transmission.The request dynamic is carried out, such as by clearly controlling Signaling.This for example can be by allowing the UL of each transmission to dispatch to permit containing indicating whether request HARQ feedback and if it is Which HARQ Rx process should be carried out by the added field of report status.Carried in some embodiments, it may be possible to also exist The independent scheduling of HARQ requests is permitted.

Each HARQ Rx process（Should be for its report status）Addressing may carry out in the following way：A) for example Clearly carried out by bitmap；Or b）By defining regulation by by the regular collection of which kind of order filling HARQ procedure and so HARQ procedure is only indicated afterwards（For its request feedback）Sum；Or c）Subframe scope in by providing that UL permits, and Then UE is reported in all HARQ procedures received in those subframes.HARQ RX processes（Should be to its report status）It is clear and definite Indicate include instruction process scope, wherein the scope for example by start HARQ procedure identifier and some HARQ procedures or Indicated by beginning and end HARQ procedure identifier.

The HARQ feedback of specific HARQ process is clearly asked by allowing network, rather than allows UE independently to provide it, More preferable control is realized in HARQ feedback report.This enables the network to know which HARQ procedure is real with higher reliability Require to retransmit on border, so as to reduce the re-transmission of the waste in other HARQ procedures due to incomplete HARQ information.More enter one Thus step, different groups of bits of coded and forward error correction position are being transmitted using the redundancy versions retransmitted in each re-transmission of data block In the system of conjunction, the optimum redundancy version that can be retransmitted with higher probability selection.

More preferable HARQ controls also make system be less susceptible to undetected downlink allowance, i.e. PDCCH/ePDCCH Decoding failure（Especially for re-transmission）.

In addition, by ensuring to provide the subset of HARQ Rx processes about not being the whole of HARQ Rx processes and requiring nothing more than Feedback, HARQ reports size is reduced, and therefore saves uplink transmission resource.

According to several embodiments of presently disclosed technology, problem as described above passes through from network to UE transmitting requests The solution of the signal of the HARQ feedback of the HARQ procedure indicated a bit is solved.The method in network by not being properly received instead The re-transmission of feedback is realized in the case of feedback and the problem of there is irregular HARQ feedback for dynamic TDD is solved, while also carrying The mechanism for having supplied robust HARQ to report.This asynchronous " on demand " method for reporting is additionally contemplates that the processing time the loosened constraint in UE.

According to some embodiments of presently disclosed technology, UL scheduling approval messages pass through for being explicitly indicated in UE HARQ Rx procedure request HARQ feedbacks " HARQ feedback request " field amendment.It is probably for regular to dispatch approval message Uplink data is transmitted, or is used as the specific allowance for being exclusively used in scheduling uplink control information.In the later case, adjust Degree allowance can be comprised in downlink scheduling assignment.It is anti-that the reception of such field and then triggering UE transmit HARQ to network Feedback.

Figure 5 illustrates the example of the HARQ feedback process of this method according to a HARQ procedure --- comprising into Work(receives downlink allocation, down link data, up-link allowance and the transmission of HARQ feedback.

In downlink subframe, given UE downlink allocation is transmitted using PDCCH or ePDCCH（DL is assigned）.This Each warning UE of a little DL assignments transmits UE down link data on physical down link sharing channel (PDSCH).Such as Seen in figure, the certain point after specific downlink transmission reuses PDCCH or ePDCCH, in descending chain The up-link that same UE is transmitted on road is permitted（UL permits）.Permit including HARQ in this UL shown in subframe 25 in Figure 5 Feedback request.Certain amount（g）Subframe after, UE transmission corresponding to one or more HARQ procedures HARQ feedback, each HARQ procedure corresponds to the downlink transmission earlier to UE.

In the example shown in Fig. 5, indicated from delay of the HARQ feedback request until transmitting HARQ feedback is received by g； In certain embodiments, this parameter can be that system is related.It should be appreciated that Fig. 5 illustrates single HARQ procedure. In LTE and in other systems, several processes can be activity simultaneously so that system is being dispatched to UE and sending additional data Without waiting for before until HARQ procedure terminates.

In certain embodiments, UL permits including " HARQ feedback request " field, and it, which is included in, is used for uplink scheduling The existing down link control information permitted（DCI）Form（That is DCI format 0 or 4）In.This can expand existing by using added field There is form progress.In other embodiments, " HARQ feedback request " field, which is comprised in, will be used for except available DCI format today In the new DCI format that uplink scheduling outside 0 and 4 is permitted.In other embodiments again, " HARQ feedback request " field quilt Included in the one or more existing DCI formats assigned for downlink scheduling.This can expand existing by using added field There is form to carry out.In other embodiments again, pass through the additional radio Network Temporary Identifier to UE offers for this purpose Symbol（RNTI）To signal " HARQ feedback request ".No matter when this new RNTI is used in DCI message, belong to existing The position of existing field is reusable in the additional information required by " HARQ feedback request " in DCI format.

The content of " HARQ feedback request " field can change from one embodiment of current technology to another embodiment.One In a little embodiments, " HARQ feedback request " field is the bit field for simply indicating whether to ask HARQ feedback.This can be to UE Indicate the feedback of all HARQ procedures of request.In other embodiments, " HARQ feedback request " field is that size is equal to HARQ mistakes The bitmap of journey sum.It is assumed that this is T, then this bitmap can use 0...T-1 indexes so that in index t setting in this bitmap Position（Such as place value is 1）It is meant that asking to feed back for the HARQ procedure with index t.Similarly, in certain point in bitmap Clearing position（Such as place value is 0）It is meant that not feeding back the HARQ procedure by being provided for corresponding to the point.

In other embodiments again, " HARQ feedback request " field is encoded into the relevant particular number HARQ procedure of instruction （UE should provide feedback for it）Information.As an example, it may be encoded as being interpreted { 0,2,20, All } 2 information fields.In the case, " All " means report all HARQ procedures, and " 0 " means send out Deliver newspaper announcement.Also require that network ensures to use HARQ procedure by pre-defined order in order to which this is fully usable, such as always It is free HARQ procedure of the distribution with minimum call number.Then network also needs to ensure had the time to complete it in request It is preceding to be carried out in the time that reconfigures any HARQ procedure, to avoid confusion.

In certain embodiments, by providing actual HARQ procedure quantity（It is one or more）, to single or multiple selections Procedure request " HARQ feedback request ".In certain embodiments, " HARQ feedback request " field indicates process scope.So as to, For example, it there can be the form comprising initial value t and scope r, indicate report the HARQ mistakes numbered from t to t+r-1 to UE Journey.

In other embodiments again, " HARQ feedback request " field indicates subframe scope, so as to indicate to connect within the range The corresponding HARQ instance Rx set of procedures of receipts.So as to for example, " HARQ feedback request " can include table in some of these embodiments The subframe k of the last-minute plea of skew for the reception subframe n away from allowance is stated, and also comprising the subframe that be included in report Number.Then hui reports all subframes from n+k-m-1 to n+k.

In various embodiments, the HARQ feedback transmitted by UE can include the bright of HARQ Rx processes (reporting it feedback) True identifier.In certain embodiments, the HARQ feedback of transmission can include " ReportSFN " timestamp, and it indicates one of them Or multiple HARQ procedures（Feedback is reported it）Each subframe numbers.

Give the example for being described in detail above HARQ feedback report and the technology handled, it should be appreciated that can be more typically Apply these technologies in ground.
